Tooth sensitivity is a condition that occurs when the sensitive layer of the tooth, also called dentin, becomes exposed. The tooth has an outer layer of covering called the enamel.
Beneath the enamel is a cementum, which covers the root of the tooth. Right beneath this layer is dentin, which contains the nerve roots. When these nerve roots are exposed, the teeth become exposed to all kinds of stimuli, which is perceived in the mouth as sensitivity.
How to Know if You Have Sensitive Teeth
A common presentation of tooth sensitivity is an uncomfortable pain when drinking or eating foods of extreme temperatures. Sometimes the sensitivity is triggered by the ingestion of ordinary food. Tooth sensitivity is very common and should always be a cause of concern. The dentin may be exposed in conditions like dental cavity and recession of the gum in gum disease. All these conditions should be first and foremost identified and treated by our dentists before the decision to use a desensitizing toothpaste is made.
How Desensitizing Toothpaste Works
What commercial desensitizing agents do is coat the tooth and prevent the dentin from exposure to the extremes of temperate and food substances. They also reduce the sensitivity of the nerve endings to stimuli, hence reducing sensitivity overall.
Potassium nitrate is one of the primary components of desensitizing toothpaste. It lodges its way to the tooth pulp, where it enters the nerve roots and prevents the transmission of the pain signal all the way to the brain. This is by using potassium ions. Strontium chloride is another active ingredient of desensitization paste. It works by blocking the connecting tubules to the pulp. This returns the pulp to the initial “covered up” state. Desensitizing toothpaste is affordable and easy to use.
It is important to note that the desensitizing power cannot be achieved with one brush. Continuous use will eventually lead to the return to normal state. Consult us if you have any questions on desensitizing toothpastes.
